Answer:The area of a circle is the number of square units inside that circle. If each square in the circle to the left has an area of 1 cm2, you could count the total number of squares to get the area of this circle.
Step-by-step explanation:The area of a circle can be found by multiplying pi ( π = 3.14) by the square of the radius.
If a circle has a radius of 4, its area is 3.14*4*4=50.24.
If you know the diameter, the radius is 1/2 as large
